The experiments show that intrabronchial insufflation of a culture of virulent pneumococcus killed by heat and still containing stainable organisms produces an inextensive, mild, patchy, superficial inflammation of the lung tissue bearing no similarity to the lesions produced by the living pneumococcus, and that insufflation of sterile bouillon causes a pronounced congestion of the lung tissue ...

BACKGROUND AND STUDY AIMS Compared with air insufflation, water exchange and carbon dioxide (CO2) insufflation have been shown to reduce colonoscopy discomfort; however, head-to-head studies of the two methods are lacking. We aimed to compare water exchange and CO2 insufflation directly with regard to pain during primary unsedated colonoscopy. METHODS Patients willing to undergo unsedated col...

Many patients experience pain and discomfort after colonoscopy. Carbon dioxide (CO(2)) can reduce periprocedural pain although air insufflation remained the standard procedure. The objective of this double-blinded, randomized controlled trial was to evaluate whether CO(2) insufflation does decrease pain and bloating during and after colonoscopy compared to room air. Methods. 219 consecutive pat...

In the era of therapeutic endoscopy, a new device for precise cutting and simultaneous hemostasis is required. Laser technology allows immediate vaporization of tissue. The thulium laser is a new type of surgical laser. It emits a continuous 2-μm wavelength delivered through a thin, flexible laser fiber. Its penetration depth is approximately 0.25 mm, which is suitable for tissue resection with...

BACKGROUND AND OBJECTIVES Within recent years, the insufflation technique for laparoscopy has become more important with high flow insufflators (> or = 30 L/min) and high gas turn over (> or = 800 L/procedure). Increased amounts of carbon dioxide (CO2) gas used can lead to laparoscopic hypothermia. We studied the insufflator with versus insufflators without internal gas heating (inside insuffla...

BACKGROUND/AIMS Endoscopic submucosal dissection (ESD) with air insufflation is commonly used for the staging and treatment of early gastric carcinoma. However, carbon dioxide (CO2) use has been shown to cause less post-procedural pain and fewer adverse events. The objective of this study was to compare the post-procedural pain and adverse events associated with CO2 and air insufflation in ESD....

Measurements of cardiac output, mean arterial pressure, central venous pressure, and heart rate were made in seven patients undergoing laparoscopy. Measurements were made before and after insufflation of the peritoneum with carbon dioxide, and again after intravenous injection of oxprenolol 2 mg. No significant change in cardiac output followed peritoneal insufflation, but there was a significa...

OBJECTIVE To investigate the effect of deep lung insufflations on maximum insufflation capacities (MICs) and peak cough flows (PCFs) for patients with neuromuscular disease. METHOD Forty-three patients with neuromuscular disease were trained in stacking delivered volumes of air to deep lung insufflation and were prescribed a program of air stacking once their vital capacities (VCs) were noted...

One of the methods used to reduce pain and discomfort during colonoscopy is insufflation of carbon dioxide instead of air. However, the actual benefit of carbon dioxide insufflation is not unequivocally proven. The aim of the study was to evaluate the advantages of carbon dioxide insufflation during screening colonoscopy. A total of 200 patients undergoing screening colonoscopy between 2010 and...
